What it does

Spk Start Agent Surface is an agent skill from spec-kitty/spec-kitty. Choose the correct Spec Kitty workflow for Codex CLI, Claude Code, and supported slash-command or command-skill harnesses.

Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Hooks and plugins. The repository describes itself as: Spec-Driven Development with organizational governance. Specs tell AI agents what to build; Charter governs how they build it. Git-native missions, enforceable workflows, and… The licence is MIT.

When your agent uses it

  • Tasks that involve Hooks and plugins

Example prompts

  • “/spk-start-agent-surface”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify the surface: command line, Codex, Claude Code, slash-command host,
  2. Check whether slash commands, skills, and local filesystem access are
  3. If commands are missing, route to spk-admin-setup-doctor.

What it can do on your machine

Read from SKILL.md and the folder at commit e533131. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spk Start Agent Surface loads about 270 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 119 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~270

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

spk-start-agent-surface

Use this skill when the question is about where Spec Kitty works, how commands or skills appear in a specific agent, or why behavior differs by surface.

Checks

  1. Identify the surface: command line, Codex, Claude Code, slash-command host, or command-skill host.
  2. Check whether slash commands, skills, and local filesystem access are available in that surface.
  3. If commands are missing, route to spk-admin-setup-doctor.
  4. If the user needs compatibility research, use the legacy spec-kitty-agent-surface-research skill when installed.

Guidance

  • Prefer local CLI workflows when the surface can read/write the repo.
  • Prefer command skills for slash-command execution.
  • Prefer spk-* skills for explanation, recovery, and orchestration.
  • Do not assume cloud-hosted agents can access local .kittify/, kitty-specs/, or .worktrees/ paths.
